摘要:
The present connector press-fitting apparatus comprises a press-fitting head, a press-fitting block, a cylinder, a positional detector, a pin detector, and a controller. The press-fitting head comes into contact with the connector, and attaches to and detaches from this connector. The press-fitting block supports the press-fitting head elastically. The cylinder is capable of moving the press-fitting block freely in a vertical direction, lowers the press-fitting block, and press-fits pins of the connector into a printed board which is arranged at a press-fitting position. The positional detector detects the displacement of the press-fitting head. The pin detector detects at least one pin lead end part projecting below the printed board in accordance with the press-fitting operation of the connector by means of the cylinder. The controller detects when the press-fitting block is in a standard insertion position by means of the positional detector, and at the point in time at which the pin detector has detected at least one pin lead end part, the controller lowers the press-fitting block by means of the cylinder and press-fits the pin base end parts of the connector into the printed board.

An electric motor that is fixed to a revolving frame, an electrical equipment that is supported by the revolving frame by using a vibration absorption mount, and a cable for establishing a connection between the electric motor and the electrical equipment are provided. A connector mounting member having an outer shape smaller than that of a box is provided in the box of the electrical equipment, and an equipment-side connector is provided in the connector mounting member. A cable-side connector of the cable is connected to the equipment-side connector, and a cable end portion of the cable is fixed to the box by a clamp member. As a result, the vibration that is transmitted to the cable can be matched with the vibration that is transmitted to the cable-side connector.

An electric work vehicle is provided in which the length of a high-tension cable connecting an electric motor included in a slewing motor with an inverter for controlling the electric motor can be set to be comparatively short. A region on a main frame is divided into three regions consisting of a center region, a first side region, and a second side region, via a first vertical rib and a second vertical rib. A slewing hydraulic motor and a slew assist electric motor, which constitute the slewing motor, are disposed in the center region, and an inverter for controlling the slew assist electric motor is disposed in a position near the second vertical rib in a second tool chamber provided in the second side region.

When temperature is low, a low-temperature mode is selected, followed by the activation of the heating mode functionality 25a of a PCU 25. Specifically, the PCU 25 sets the ratio of energy recovered by a capacitor 23 to be equal to or greater than the largest value of the energy recovery ratios of the capacitor 23 in a normal mode (e.g., assist motor 22:capacitor 23=2:8). Thus, more energy is stored on the capacitor 23 than in the normal mode, helping the capacitor 23 generates heat. As a result, the liquid temperature of the coolant is increased, and its viscosity is reduced accordingly. As above, the invention provides a simple cooling system to be mounted on a hybrid working machine, which is capable of preventing decreases in energy efficiency at low temperature.
